<p>A field to index full-text values, such as the body of an email or the
description of a product. These fields are <code class="literal">analyzed</code>, that is they are passed through an
<a class="xref" href="analysis.html" title="Text analysis">analyzer</a> to convert the string into a list of individual terms
before being indexed. The analysis process allows Elasticsearch to search for
individual words <em>within</em>  each full text field.  Text fields are not
used for sorting and seldom used for aggregations (although the
<a class="xref" href="search-aggregations-bucket-significanttext-aggregation.html" title="Significant Text Aggregation">significant text aggregation</a>
is a notable exception).</p>
<p>If you need to index structured content such as email addresses, hostnames, status
codes, or tags, it is likely that you should rather use a <a class="xref" href="keyword.html" title="Keyword datatype"><code class="literal">keyword</code></a> field.</p>
<p>Below is an example of a mapping for a text field:</p>
<div class="pre_wrapper lang-console">
<pre class="programlisting prettyprint lang-console">PUT my_index
{
  "mappings": {
    "properties": {
      "full_name": {
        "type":  "text"
      }
    }
  }
}</pre>

</div></div></div>
<p>Sometimes it is useful to have both a full text (<code class="literal">text</code>) and a keyword
(<code class="literal">keyword</code>) version of the same field: one for full text search and the
other for aggregations and sorting. This can be achieved with
